Transmit Rate: Sets the length of time between sonar pings.

Increasing the transmit rate increases the scroll speed, but it

may also increase self-interference.

Reducing the transmit rate increases the spacing between

transmit pulses and can resolve self-interference.

Transmit Power: Reduces transducer ringing near the surface.

A lower transmit power value reduces transducer ringing, but

can also reduce the strength of the returns.

Filter Width: Defines the edges of the target. A shorter filter

more clearly defines the edges of the targets but may allow

more noise. A longer filter creates softer target edges and

may also reduce noise.

Transducer Diagnostics: Shows details about the transducer.

Flip Left/Right: Switches the

SideVü view orientation from left

to right.

Install Depth: Sets the depth below the water line where the

Panoptix transducer is mounted. Entering the actual depth at

which the transducer is mounted results in a more accurate

visual presentation of what is in the water.

Flipped: Sets the orientation of the

Panoptix sonar view when

the down view transducer is installed with the cables pointing

toward the port side of the boat.

Beam Width: Sets the width of the Panoptix transducer beam.

Narrow beam widths allow you to see deeper and farther.

Wider beam widths allow you to see more coverage area.

Use AHRS: Enables the internal attitude heading and reference

system (AHRS) sensors to detect the installation angle of the

Panoptix transducer automatically. When this setting is

turned off, you can enter the specific installation angle for the

transducer using the Pitch Angle setting. Many forward view

transducers are installed at a 45-degree angle and down

view transducers are installed at a zero-degree angle.

Sonar Recordings

Recording the Sonar Display

NOTE: Not all models support sonar recording.

Insert a memory card into the card slot.

From a sonar view, select Menu > Sonar Setup >

Sonar

Recording > Record Sonar

15 minutes of sonar recording uses approximately 200 MB of

space of the inserted memory card. You can record sonar

until the card reaches capacity.

Stopping the Sonar Recording

Before you can stop recording sonar, you must begin recording

it (Recording the Sonar Display,

page

24).

From a sonar view, select Menu > Sonar Setup > Sonar

Recording > Stop Recording.

Deleting a Sonar Recording

Insert a memory card into the card slot.

From a sonar view, select Menu > Sonar Setup > Sonar

Recordings

> View Recordings

Select a recording.

Select

Delete.

Playing Sonar Recordings

Before you can play back the sonar recordings, you must

download and install the HomePort

™

application and record

sonar data onto a memory card.

Remove the memory card from the device.

Insert the memory card into a card reader attached to a

computer.

Open the

HomePort application.

Select a sonar recording from your device list.

Right-click the sonar recording in the lower pane.

Select

Playback.

Radar

WARNING

The marine radar transmits microwave energy that has the

potential to be harmful to humans and animals. Before

beginning radar transmission, verify that the area around the

radar is clear. The radar transmits a beam approximately 12°

above and below a line extending horizontally from the center of

the radar.

When the radar is transmitting, do not look directly at the

antenna at close range; eyes are the most sensitive part of the

body to electromagnetic energy.

When you connect your compatible chartplotter to an optional

Garmin

marine radar, such as a

GMR

™

Fantom

™

radar or a

GMR

24 xHD, you can view more information about your

surroundings.

The radar transmits a narrow beam of microwave energy as it

rotates to a 360° pattern. When the transmitted energy contacts

a target, some of that energy is reflected back to the radar.

Changing the Radar Mode

From a combination screen or SmartMode layout with radar,

select Menu

> Radar Menu > Change Radar

Select a radar mode.

Transmitting Radar Signals

NOTE:

As a safety feature, the radar enters standby mode after

it warms up. This gives you an opportunity to verify the area

around the radar is clear before beginning radar transmission.

With the chartplotter off, connect your radar as described in

the radar installation instructions.

Turn on the chartplotter.

If necessary, the radar warms up and a countdown alerts you

when the radar is ready.

Select

Radar.

Select a radar mode.

A countdown message appears while the radar is starting up.

Select Menu >

Transmit Radar

Stopping the Transmission of Radar Signals

From a radar screen, select Menu > Radar To Standby.

TIP: Press >

Radar To Standby

from any screen to

quickly stop radar transmission.

Setting Up the Timed Transmit Mode

To help conserve power, you can set up time intervals in which

the radar will transmit and not transmit (standby) signal

transmissions.

NOTE:

This feature is not available in dual radar modes.

From a radar screen, select Menu > Radar Options > Timed

Transmit.

Select

Timed Transmit to enable the option.

Select

Stdby Time, enter the time interval between radar

signal transmissions, and select Done.

Select Transmit Time

, enter the duration of each radar

signal transmission, and select Done.

Enabling and Adjusting a Radar No Transmit Zone

You can indicate an area within which the radar scanner does

not transmit signals.

NOTE:

This feature is not available on all radar and chartplotter

models.
